Field Trip to Trona, CA.  October, 11th - 13th.

Trona is located in the Searles Valley on Hwy 178 in the Greater Mojave Desert and has valley views of the Slate and Argus Mountains.

Trona is home to Searles Lake playa. Searles Lake is one of a chain of Pleistocene lakes which were formed during the Ice Ages. The dry lake bed contains a plethora of sodium and potassium minerals of the carbonate, sulfate, borate and halide classes, due to long sedimentation and evaporation processes which occurred over a period of about 150,000 years.
